Great news for you with the Warhammer upper sail; now I make the same set of fine additions for your sub just in your size too (you can thank Thom)
These are just a bit smaller in diameter to fit your new resin parts (2.476mm diameter as my other parts are 2.8mm)

please contact me by email
The price is still the same at $36.50 for all 6 parts
2 scopes
2 gun barrels
2 propeller shafts
